Write a paragraph describing how the Mandate of Heaven and legalism conflicted with each other. (Has to be long answer or paragraph)

The Zhou created the Mandate of Heaven: the idea that there could be only one legitimate ruler of China at a time, and that this ruler had the blessing of the gods. They used this Mandate to justify their overthrow of the Shang, and their subsequent rule. If a king ruled unfairly he could lose this approval, which would result in his downfall. Overthrow, natural disasters, and famine were taken as a sign that the ruler had lost the Mandate of Heaven ... The Zhou claimed that their rule was justified by the Mandate of Heaven.
